8 Claimsy (01.198-220) This invention relates to improvements in ishaker conveyer trough connecting means and has as its principal objectsto provide a simplied, novel form of connecting means for detach- .ablyconnecting adjacent ends of the troughs of a shaker conveyer together ina more efficient and expeditious manner than formerly.

A more specific ,object of my invention is to provide a connecting meansfor connecting adjacent ends of a pair of shaker conveyer troughstogether, which also serves to form a connecting andsupport means forthe troughs on a reciprocably movable support therefor.

Other objects of my invention will appear from time to time as thefollowing specification proto the accompanying Y Figure 3 is afragmentary transverse sectional View showing certain details of theclamping means and the supporting connection between the reciprocablymoving support and the troughs of the conveyer;

. Figure 8 is a fragmentary plan View illustrating amodified form of myinvention; and

Figure 9 is a View in side elevation of the form of my invention shownin Figure 8.

In the embodiment of my invention illustrated in the drawings, a pairV0f shaker conveyer troughs l0, I0 are shown as being connected inabutting relation with respect to each other. Said troughs are each of ausual construction having a hat bottom and outwardly inclinedflared-sides |2, I2, and while shown as being abutting troughs, may alsobel of a common form connected together in overlapping relation.

Adjacent ends of the troughs I0, I0 are reciprocably supported on areciprocable supporting means, which is herein shown as being a ballframe I3. Said Iball frame may be of any usual construction well knownto those skilled in the art and as herein shown includes a lower framemember i4 held in xed relation with respect to the ground as by jacksinterposed between said frame member and the mine roof (not shown). Anupper frame member I5 is mounted on said lower frame member forreciprocable movement with respect thereto on balls I6, I6, in the usualmanner.

The upper frame member I5 of the ball frame I3 is provided with a pairof oppositely spaced longitudinally extending upright lugs Il, I1, to

Vwhich are pivotally connected a pair of transversely extendingconnecting ears I8, I8 on transversely extending pivotal pins I9, IS,secured to and projecting outwardly from said ears (see Figure 4). Saidconnecting ears I8, I8 are each provided with an aperture 20, which extends therethrough in a direction longitudinally of the troughs I0, I0.Said apertures form a connecting means between said troughs and saidball frame, and are adapted to have pins 2|, 2| extend therethrough, forsupporting adjacent ends of said troughs on said ball frame. Said pinsproject longitudinally from the ends of connecting members 24, 24, whichare secured to and project laterally from opposite sides of one end ofone of the troughs I0. Opposite faces of said connecting ears areabutted by engaging faces 25, 25, of said connecting member 24, andengaging faces 2t, 26 of connecting members 21, 2l, which are secured toand project laterally from opposite sides of an adjacent end of theother trough I. Said pins 2|, 2| also extend through advance end walls28, 28 Vof said connecting members 2l, 21 to hold said connectingmembers in vertical alignment.

The clamping means for connecting adjacent ends of the troughs I0, I0together andclamping lsaid troughs tothe connecting ears I8, `I8,are thesame for each side of-said troughs, so the clamping means Vand ,theconnection between said clamping means and the connecting members 24 and2l on one sideof said troughs only'will here be described in detail. Theconnecting member 2 is provided with an open portion 29, extending tothe rear ofthe advance wall 28'and within which is adaptedto .extend ahooked end of a clamping'member 3U. Said clamping member is .2 of asubstantially C-shaped formation, and the inner surface of said hookedend has a concave substantially ball-shaped engaging surface 32, whichis adapted to engage a curved substantially ball-shaped engaging face33, projecting from the outer end of the Wall 28, in a directionopposite from the engaging face 25. The adjacent connecting member 24 isprovided with a curved convex engaging face 34, curved in both verticaland horizontal directions to form a segment of a sphere. The transverseengaging surface of' said engaging face is struck from a plurality ofarcs, the radii of which are of a greater length than the radius of thelargest arc from which the face 33 of the connecting member 21 isstruck. Said curved engaging face 34 is adapted to be engaged by acorresponding inner curved engaging face 35 of the clamping member 30.

Thus, when the concave surface 32- o-f saidA clamping member hasengagement with the engaging face 33, said engaging face 33 will serveas fulcrum for said clamping member. When said inner face 35 is engagedwith the curved engaging face 34 and said clamping member is moved in adirection towards the laterally projecting connecting member 24, aboutsaid fulcrum, said clamping member will urge said connecting members andadjacent ends of the troughs Ill., I towards each other.

When said clampingmember has been moved inwardly about its fulcrum a.distance suincient to fully engage. and clamp the faces 25 and- 26 withopposite sidesk of the connecting ear I8 of the ball `:frame I3, it willhold said connecting members and adjacent ends of said troughs inclamped relation with respect to said connecting ears I8, I8 of the ballframe I3.

The means for moving the clamping member 30 about the fulcrurn formed.by the ball-shaped engaging face 33 of the connecting member 2'! isherein shown as being a T-shaped bolt 36, the head of which is adaptedto be inserted through a longitudinally extending slot 39. formed in anouter wall portion 40 of the connecting member 24. When the head of saidbolt has been inserted .through said slot it may be turned. to avertically extending position so as to engage the inside of said wallportion. Said bolt is also adapted to extend through an. enlargedaperture 4I formed in an outer end of the clamping member 3U, oppositethe concave engaging surface 32. A spring 42 abuts the outer side ofsaid clamping member and is interposed between the outer side of saidclamping member and a nut43, threaded on the end. of said bolt.

The T-shaped bolt is. normally. adapted to be connected to the clamping.member 30 at all times, the nut 43 being locked on said. bolt by peeningover. the slotted end thereof. The clamping device and boltare thusremoved from the troughs as. a unit, when they are disconnected, byfirst loosening saidnut and then turning. said bolt until the headthereof will fit throughthe s101139.

In Figures 8 and.9 a modified. form of clamping device is shown whichserves to support an end trough ID of the conveyer on the ball frame I3.In this form. of the invention a clamping device 44 is provided. Saidclamping device is ofv a C- shaped formation and is similar to theclamping device 3D, but has an apertured outer. end 45, the aperturedportion of which ts around the projecting pin2I of the connecting member24. Said clamping device is provided With-a. curved er1-` gaging`surface. 46,. adapted to engage theV curved engaging surface 34 of theconnecting member 24, and is moved in a direction towards saidconnecting member by means of a T-shaped bolt 41 having a nut 48 on theend thereof, in a manner similar to which the clamping member 30 ismoved into clamping engagement with the engaging face 34 of itsassociated connecting member 24.

One inner end of said clamping member thus abuts an outer face of theconnecting ear I8 of the ball frame I 3 and the other inner end of saidclamping member abuts the engaging face 34 of the connecting member 24,and said clamping member serves to clamp said connecting ear to theengaging face 25 of said connecting member so said connecting ear willsupport one side of the trough ID on the ball frame I3, it beingunderstood that the two connecting ears serve to support the adjacentend of said trough on said ball frame.

While I have herein shown and described one form in which my inventionmay be embodied, it will be understood that the construction thereof andthe arrangement of the various parts may be altered without. departingfrom the spirit and scope thereof. Furthermore, I do not wish to beconstrued as limiting myl invention to the specic embodimentillustrated, excepting as it may be limited. in the appended claims..
